Facebook is to use footage from police body cameras to train its content moderation programmes in response to claims that it failed to prevent images of the New Zealand mosque shootings spreading across its platform earlier this year.
The social media giant will provide London’s Metropolitan Police with body cameras “for firearms training exercises”, the Financial Times reports. It also plans to supply US law enforcement agencies with wearable cameras.
Images captured by the cameras will then be used to train artificial intelligence (AI) powered content moderation systems to more quickly identify and remove first-person footage of real-life shooting incidents, the FT adds.

The agreement is the latest move by Facebook to limit extreme content on its platform. In May, the company employed a “one-strike policy”, where users sharing violent content - such as a statement from an extremist group “without context” - would be blocked from using Facebook Live, says Sky News.
Why Facebook was criticised for its handling of the New Zealand shootings
On 15 March, 51 people were killed when a “lone attacker opened fire during Friday prayers” at two mosques in Chirstchurch, The Sun says.
The gunman live-streamed the attack for 17 minutes through Facebook, where the footage remained for a further 12 minutes before being taken down, says Sky News. Some 200 people watched the stream live, though 1.5 million videos of the attack were uploaded and subsequently removed.
Facebook was criticised for failing to identify the stream and for leaving footage of the attack on its platform “weeks” after the event, according to Engadget.
How police footage could prevent future violent live-streams
In its defence, Facebook said in a statement that its moderation algorithms “did not have enough content depicting first-person footage of violent events to effectively train our machine learning technology.
“That’s why we’re working with government and law enforcement officials in the US and UK to obtain camera footage from their firearms training programs – providing a valuable source of data to train our systems.”
The Met Police’s assistant commissioner for specialist operations, Neil Basu, believes that Facebook’s cameras may also benefit police “in their response to such incidents”, The Daily Telegraph reports.
The footage recorded by the Met will also be distributed through the Home Office to other tech firms developing software aimed at identifying mass shootings broadcast on social media, the newspaper adds.
